FIELD OF THE INVENTION

The present invention relates to the field of antimicrobial prophylaxisand therapy. In particular the present invention relates to novelproteins and polynucleotides derived from Campylobacter jejuni. Theinvention further relates to vectors comprising the polynucleotides,transformed host organisms expressing the polynucleotides, antibodies(mono- or polyclonal) specific for the polypeptides as well asdiagnostic, prophylactic and therapeutic uses and methods. Finally, alsomethods of preparation are part of the invention.

BACKGROUND OF THE INVENTION

C. jejuni is a bacterium commonly associated with poultry, since itnaturally colonises the digestive tract of many bird species.Contaminated drinking water and unpasteurized milk provide an efficientmeans for distribution in human populations. Contaminated food is amajor source of isolated C. jejuni infections, with incorrectly preparedmeat and poultry normally being the source of the bacteria.

Infection with C. jejuni usually results in enteritis, which ischaracterised by abdominal pain, diarrhea, fever, and malaise. Thesymptoms usually persist for between 24 hours and a week, but may belonger. Diarrhea can vary in severity from loose stools to bloodystools. The disease is usually self-limiting. However, it does respondto antibiotics. Severe (accompanying fevers, blood in stools) orprolonged cases may require ciprofloxacin, erythromycin, azithromycin ornorfloxacin. The drug of choice is usually erythromycin. About 90% ofcases respond to ciprofloxacin treatment. Fluid and electrolytereplacement may be required for serious cases.

The first full-genome sequence of C. jejuni was performed in 2000(strain NCTC11168) with a circular chromosome of 1,641,481 base pairs.

As mentioned, C. jejuni infections may successfully be treated byadministration of antibiotics to patients in need thereof, but thatwould not prevent acute illness. Further, due to careless or thoughtlessuse of powerful antibiotics, many pathological germs, including C.jejuni become resistant against antibiotics over time. In particular inhospitals, treatment with antibiotics can prove inadequate: not onlywill a C. jejuni infection be life-threatening for patients that alreadysuffer from other health problems meaning that treatment withantibiotics may simply be non-effective within the relevant time-span,but in addition antibiotic-resistant C. jejuni strains will alsowithstand treatment with those antibiotics used as the initial choice intreatment. There is thus a need to provide alternatives to currenttreatment regimens. Also, infection with C. jejuni is associated withreactive arthritis and Guillain-Barré Syndrome.

Vaccination is considered to be a very effective method of preventinginfectious diseases in human and veterinary health care. Vaccination isthe administration of immunogenically effective amounts of antigenicmaterial (the vaccine) to produce immunity to a disease/disease-causingpathogenic agent. Vaccines have contributed to the eradication ofsmallpox, the near eradication of polio, and the control of a variety ofdiseases, including rubella, measles, mumps, chickenpox, typhoid fever.

Before “the genomic era”, vaccines were based on killed or liveattenuated, microorganisms, or parts purified from them. Subunitvaccines are considered as a modern upgrade of these types of vaccine,as the subunit vaccines contain one or more protective antigens, whichare more or less the weak spot of the pathogen. Hence, in order todevelop subunit vaccines, it is critical to identify the proteins, whichare important for inducing protection and to eliminate others.

An antigen is said to be protective if it is able to induce protectionfrom subsequent challenge by a disease-causing infectious agent in anappropriate animal model following immunization.

The empirical approach to subunit vaccine development, which includesseveral steps, begins with pathogen cultivation, followed bypurification into components, and then testing of antigens forprotection. Apart from being time and labour consuming, this approachhas several limitations that can lead to failure. It is not possible todevelop vaccines using this approach for microorganisms, which cannoteasily be cultured and only allows for the identification of theantigens, which can be obtained in sufficient quantities. The empiricalapproach has a tendency to focus on the most abundant proteins, which insome cases are not immuno-protective. In other cases, the antigenexpressed during in vivo infection is not expressed during in vitrocultivation. Furthermore, antigen discovery by use of the empiricalapproach demands an extreme amount of proteins in order to discover theprotective antigens, which are like finding needles in the haystack.This renders it a very expensive approach, and it limits the vaccinedevelopment around diseases, which is caused by pathogens with a largegenome or disease areas, which perform badly in a cost-effectiveperspective.

DETAILED DISCLOSURE OF THE INVENTION Definitions

The term “polypeptide” is in the present context intended to mean bothshort peptides of from 2 to 10 amino acid residues, oligopeptides offrom 11 to 100 amino acid residues, and polypeptides of more than 100amino acid residues. Furthermore, the term is also intended to includeproteins, i.e. functional biomolecules comprising at least onepolypeptide; when comprising at least two polypeptides, these may formcomplexes, be covalently linked, or may be non-covalently linked. Thepolypeptide (s) in a protein can be glycosylated and/or lipidated and/orcomprise prosthetic groups.

The term “subsequence” means any consecutive stretch of at least 3 aminoacids or, when relevant, of at least 3 nucleotides, derived directlyfrom a naturally occurring amino acid sequence or nucleic acid sequence,respectively

The term “amino acid sequence” s the order in which amino acid residues,connected by peptide bonds, lie in the chain in peptides and proteins.

The term “adjuvant” has its usual meaning in the art of vaccinetechnology, i.e. a substance or a composition of matter which is 1) notin itself capable of mounting a specific immune response against theimmunogen of the vaccine, but which is 2) nevertheless capable ofenhancing the immune response against the immunogen. Or, in other words,vaccination with the adjuvant alone does not provide an immune responseagainst the immunogen, vaccination with the immunogen may or may notgive rise to an immune response against the immunogen, but the combinedvaccination with immunogen and adjuvant induces an immune responseagainst the immunogen which is stronger than that induced by theimmunogen alone.

“Sequence identity” is in the context of the present inventiondetermined by comparing 2 optimally aligned sequences of equal length(e.g. DNA, RNA or amino acid) according to the following formula:(N_(ref)-N_(dif))·100/N_(ref), wherein N_(ref) is the number of residuesin one of the 2 sequences and N_(dif) is the number of residues whichare non-identical in the two sequences when they are aligned over theirentire lengths and in the same direction. So, two sequences5′-ATTCGGAAC-3′ and 5′-ATACGGGAC-3′ will provide the sequence identity77,78% (N_(ref)=9 and N_(dif)=2).

An “assembly of amino acids” means two or more amino acids boundtogether by physical or chemical means.

The “3D conformation” is the 3 dimensional structure of a biomoleculesuch as a protein. In monomeric polypeptides/proteins, the 3Dconformation is also termed “the tertiary structure” and denotes therelative locations in 3 dimensional space of the amino acid residuesforming the polypeptide.

“An immunogenic carrier” is a molecule or moiety to which an immunogenor a hapten can be coupled in order to enhance or enable the elicitationof an immune response against the immunogen/hapten. Immunogenic carriersare in classical cases relatively large molecules (such as tetanustoxoid, KLH, diphtheria toxoid etc.) which can be fused or conjugated toan immunogen/hapten, which is not sufficiently immunogenic in its ownright—typically, the immunogenic carrier is capable of eliciting astrong T-helper lymphocyte response against the combined substanceconstituted by the immunogen and the immunogenic carrier, and this inturn provides for improved responses against the immunogen byB-lymphocytes and cytotoxic lymphocytes. More recently, the largecarrier molecules have to a certain extent been substituted by so-calledpromiscuous T-helper epitopes, i.e. shorter peptides that are recognizedby a large fraction of HLA haplotypes in a population, and which elicitT-helper lymphocyte responses.

A “T-helper lymphocyte response” is an immune response elicited on thebasis of a peptide, which is able to bind to an MHC class II molecule(e.g. an HLA class II molecule) in an antigen-presenting cell and whichstimulates T-helper lymphocytes in an animal species as a consequence ofT-cell receptor recognition of the complex between the peptide and theMHC Class II molecule prese

An “immunogen” is a substance of matter which is capable of inducing anadaptive immune response in a host, whose immune system is confrontedwith the immunogen. As such, immunogens are a subset of the larger genus“antigens”, which are substances that can be recognized specifically bythe immune system (e.g. when bound by antibodies or, alternatively, whenfragments of the are antigens bound to MHC molecules are beingrecognized by T-cell receptors) but which are not necessarily capable ofinducing immunity—an antigen is, however, always capable of elicitingimmunity, meaning that a host that has an established memory immunityagainst the antigen will mount a specific immune response against theantigen.

A “hapten” is a small molecule, which can neither induce or elicit animmune response, but if conjugated to an immunogenic carrier, antibodiesor TCRs that recognize the hapten can be induced upon confrontation ofthe immune system with the hapten carrier conjugate.

An “adaptive immune response” is an immune response in response toconfrontation with an antigen or immunogen, where the immune response isspecific for antigenic determinants of the antigen/immunogen—examples ofadaptive immune responses are induction of antigen specific antibodyproduction or antigen specific induction/activation of T helperlymphocytes or cytotoxic lymphocytes.

A “protective, adaptive immune response” is an antigen-specific immuneresponse induced in a subject as a reaction to immunization (artificialor natural) with an antigen, where the immune response is capable ofprotecting the subject against subsequent challenges with the antigen ora pathology-related agent that includes the antigen. Typically,prophylactic vaccination aims at establishing a protective adaptiveimmune response against one or several pathogens.

“Stimulation of the immune system” means that a substance or compositionof matter exhibits a general, non-specific immunostimulatory effect. Anumber of adjuvants and putative adjuvants (such as certain cytokines)share the ability to stimulate the immune system. The result of using animmunostimulating agent is an increased “alertness” of the immune systemmeaning that simultaneous or subsequent immunization with an immunogeninduces a significantly more effective immune response compared toisolated use of the immunogen.

Hybridization under “stringent conditions” is herein defined ashybridization performed under conditions by which a probe will hybridizeto its target sequence, to a detectably greater degree than to othersequences. Stringent conditions are target-sequence-dependent and willdiffer depending on the structure of the polynucleotide. By controllingthe stringency of the hybridization and/or washing conditions, targetsequences can be identified which are 100% complementary to a probe(homologous probing). Alternatively, stringency conditions can beadjusted to allow some mismatching in sequences so that lower degrees ofsimilarity are detected (heterologous probing). Specificity is typicallythe function of post-hybridization washes, the critical factors beingthe ionic strength and temperature of the final wash solution.Generally, stringent wash temperature conditions are selected to beabout 5° C. to about 2° C. lower than the melting point (Tm) for thespecific sequence at a defined ionic strength and pH. The melting point,or denaturation, of DNA occurs over a narrow temperature range andrepresents the disruption of the double helix into its complementarysingle strands. The process is described by the temperature of themidpoint of transition, Tm, which is also called the meltingtemperature. Formulas are available in the art for the determination ofmelting temperatures.

The term “animal” is in the present context in general intended todenote an animal species (preferably mammalian), such as Homo sapiens,Canis domesticus, etc. and not just one single animal. However, the termalso denotes a population of such an animal species, since it isimportant that the individuals immunized according to the method of theinvention substantially all will mount an immune response against theimmunogen of the present invention.

As used herein, the term “antibody” refers to a polypeptide or group ofpolypeptides composed of at least one antibody combining site. An“antibody combining site” is the three-dimensional binding space with aninternal surface shape and charge distribution complementary to thefeatures of an epitope of an antigen, which allows a binding of theantibody with the antigen. “Antibody” includes, for example, vertebrateantibodies, hybrid antibodies, chimeric antibodies, humanisedantibodies, altered antibodies, univalent antibodies, Fab proteins, andsingle domain antibodies.

“Specific binding” denotes binding between two substances which goesbeyond binding of either substance to randomly chosen substances andalso goes beyond simple association between substances that tend toaggregate because they share the same overall hydrophobicity orhydrophilicity. As such, specific binding usually involves a combinationof electrostatic and other interactions between two conformationallycomplementary areas on the two substances, meaning that the substancescan “recognize” each other in a complex mixture.

The term “vector” is used to refer to a carrier nucleic acid moleculeinto which a heterologous nucleic acid sequence can be inserted forintroduction into a cell where it can be replicated and expressed. Theterm further denotes certain biological vehicles useful for the samepurpose, e.g. viral vectors and phage—both these infectious agents arecapable of introducing a heterologous nucleic acid sequence

The term “expression vector” refers to a vector containing a nucleicacid sequence coding for at least part of a gene product capable ofbeing transcribed. In some cases, when the transcription product is anmRNA molecule, this is in turn translated into a protein, polypeptide,or peptide.

The polypeptide of the invention is in certain embodiments also fused orconjugated to an immunogenic carrier molecule; or, phrased otherwise,the polypeptide of the invention also includes such an immunogeniccarrier molecule in addition to the material derived from SEQ ID NOs.1-30. The immunogenic carrier molecule is a typically polypeptide thatinduces T-helper lymphocyte responses in a majority of humans, such asimmunogenic carrier proteins selected from the group consisting ofkeyhole limpet hemocyanino or a fragment thereof, tetanus toxoid or afragment thereof, diphtheria toxoid or a fragment thereof. Othersuitable carrier molecules are discussed infra.

In preferred embodiments, the polypeptide of the invention detailedabove is capable of inducing an adaptive immune response against thepolypeptide in a mammal, in particular in a human being. Preferably, theadaptive immune response is a protective adaptive immune responseagainst infection with C. jejuni, in particular multi-resistant C.jejuni. The polypeptide may in these cases induce a humeral and/or acellular immune response.

Epitopes

SEQ ID NOs: 1-30 include antigenic determinants (epitopes) that are assuch recognized by antibodies and/or when bound to MHC molecules byT-cell receptors. For the purposes of the present invention, B-cellepitopes (i.e. antibody binding epitopes) are of particular relevance.

It is relatively uncomplicated to identify linear B-cell epitopes—onevery simple approach entails that antibodies raised agains C. jejuni orC. jejuni derived proteins disclosed herein are tested for binding tooverlapping oligomeric peptides derived from any one of SEQ ID NO: 1-30.Thereby, the regions of the C. jejuni polypeptide which are responsiblefor or contribute to binding to the antibodies can be identified.

Alternatively, or additionally, one can produce mutated versions of thepolypeptides of the invention, e.g. version where each singlenon-alanine residue in SEQ ID NOs.: 1-30 are point mutated toalanine—this method also assists in identifying complex assembled B-cellepitopes; this is the case when binding of the same antibody is modifiedby exchanging amino acids in different areas of the full-lengthpolypeptide.

Also, in silico methods for B-cell epitope prediction can be employed:useful state-of-the-art systems for β-turn prediction is provided inPetersen B et al. (November 2010), Plos One 5(11): e15079; prediction oflinear B-cell epitopes, cf: Larsen J E P et al.

The Vectors of the Invention

Vectors of the invention fall into several categories discussed infra.One preferred vector of the invention comprises in operable linkage andin the 5′-3′ direction, an expression control region comprising anenhancer/promoter for driving expression of the nucleic acid fragmentdefined for option i) above, optionally a signal peptide codingsequence, a nucleotide sequence defined for option i), and optionally aterminator. Hence, such a vector constitutes an expression vector usefulfor effecting production in cells of the polypeptide of the invention.Since the polypeptides of the invention are bacterial of origin,recombinant production is conveniently effected in bacterial host cells,so here it is preferred that the expression control region drivesexpression in prokaryotic cell such as a bacterium, e.g. in E coli.However, if the vector is to drive expression in mammalian cell (aswould be the case for a DNA vaccine vector), the expression controlregion should be adapted to this particular use.

At any rate, certain vectors of the invention are capable of autonomousreplication.

Also, the vector of the invention may be one that is capable of beingintegrated into the genome of a host cell—this is particularly useful ifthe vector is use in the production of stably transformed cells, wherethe progeny will also include the genetic information introduced via thevector. Alternatively, vectors incapable of being integrated into thegenome of a mammalian host cell are useful in e.g. DNA vaccination.

Typically, the vector of the invention is selected from the groupconsisting of a virus, such as a attenuated virus (which may in itselfbe useful as a vaccine agent), a bacteriophage, a plasmid, aminichromosome, and a cosmid.

A more detailed discussion of vectors of the invention is provided inthe following:

Polypeptides of the invention may be encoded by a nucleic acid moleculecomprised in a vector. A nucleic acid sequence can be “heterologous,”which means that it is in a context foreign to the cell in which thevector is being introduced, which includes a sequence homologous to asequence in the cell but in a position within the host cell where it isordinarily not found. Vectors include naked DNAs, RNAs, plasmids,cosmids, viruses (bacteriophage, animal viruses, and plant viruses), andartificial chromosomes (e.g., YACs). One of skill in the art would bewell equipped to construct a vector through standard recombinanttechniques (for example Sambrook et al, 2001; Ausubel et al, 1996, bothincorporated herein by reference). In addition to encoding thepolypeptides of this invention, a vector of the present invention mayencode polypeptide sequences such as a tag or immunogenicity enhancingpeptide (e.g. an immunogenic carrier or a fusion partner that stimulatesthe immune system, such as a cytokine or active fragment thereof).Useful vectors encoding such fusion proteins include pIN vectors (Inouyeet al, 1985), vectors encoding a stretch of histidines, and pGEXvectors, for use in generating glutathione S-transferase (GST) solublefusion proteins for later purification and separation or cleavage.

Vectors of the invention may be used in a host cell to produce apolypeptide of the invention that may subsequently be purified foradministration to a subject or the vector may be purified for directadministration to a subject for expression of the protein in the subject(as is the case when administering a nucleic acid vaccine).

Expression vectors can contain a variety of “control sequences,” whichrefer to nucleic acid sequences necessary for the transcription andpossibly translation of an operably linked coding sequence in aparticular host organism. In addition to control sequences that governtranscription and translation, vectors and expression vectors maycontain nucleic acid sequences that serve other functions as well andare described infra.

1. Promoters and Enhancers

A “promoter” is a control sequence. The promoter is typically a regionof a nucleic acid sequence at which initiation and rate of transcriptionare controlled. It may contain genetic elements at which regulatoryproteins and molecules may bind such as RNA polymerase and othertranscription factors. The phrases “operatively positioned,”“operatively linked,” “under control,” and “under transcriptionalcontrol” mean that a promoter is in a correct functional location and/ororientation in relation to a nucleic acid sequence to controltranscriptional initiation and expression of that sequence. A promotermay or may not be used in conjunction with an “enhancer,” which refersto a cis-acting regulatory sequence involved in the transcriptionalactivation of a nucleic acid sequence.

A promoter may be one naturally associated with a gene or sequence, asmay be obtained by isolating the 5′ non-coding sequences locatedupstream of the coding segment or exon. Such a promoter can be referredto as “endogenous.” Similarly, an enhancer may be one naturallyassociated with a nucleic acid sequence, located either downstream orupstream of that sequence. Alternatively, certain advantages will begained by positioning the coding nucleic acid segment under the controlof a recombinant or heterologous promoter, which refers to a promoterthat is not normally associated with a nucleic acid sequence in itsnatural environment. A recombinant or heterologous enhancer refers alsoto an enhancer not normally associated with a nucleic acid sequence inits natural state. Such promoters or enhancers may include promoters orenhancers of other genes, and promoters or enhancers isolated from anyother prokaryotic, viral, or eukaryotic cell, and promoters or enhancersnot “naturally occurring,” i.e., containing different elements ofdifferent transcriptional regulatory regions, and/or mutations thatalter expression. In addition to producing nucleic acid sequences ofpromoters and enhancers synthetically, sequences may be produced usingrecombinant cloning and/or nucleic acid amplification technology,including PCR™, in connection with the compositions disclosed herein(see U.S. Pat. No. 4,683,202, U.S. Pat. No. 5,928,906, each incorporatedherein by reference).

Naturally, it may be important to employ a promoter and/or enhancer thateffectively direct(s) the expression of the DNA segment in the cell typeor organism chosen for expression. Those of skill in the art ofmolecular biology generally know the use of promoters, enhancers, andcell type combinations for protein expression (see Sambrook et al, 2001,incorporated herein by reference). The promoters employed may beconstitutive, tissue-specific, or inducible and in certain embodimentsmay direct high level expression of the introduced DNA segment underspecified conditions, such as large-scale production of recombinantproteins or peptides.

Inducible Elements include, but are not limited to MT II-Phorbol Ester(TFA)/Heavy metals (Palmiter et al, 1982; Haslinger et al, 1985; Searleet al, 1985; Stuart et al, 1985; Imagawa et al, 1987, Karin et al, 1987;Angel et al, 1987b; McNeall et al, 1989); MMTV (mouse mammary tumorvirus)-Glucocorticoids (Huang et al, 1981; Lee et al, 1981; Majors etal, 1983; Chandler et al, 1983; Lee et al, 1984; Ponta et al, 1985;Sakai et al, 1988); β-Interferon-poly(rl)×/poly(rc) (Tavernier et al,1983); Adenovirus 5 E2-E1A (Imperiale et al, 1984); Collagenase-PhorbolEster (TPA) (Angel et al, 1987a); Stromelysin-Phorbol Ester (TPA) (Angelet al, 1987b); SV40-Phorbol Ester (TPA) (Angel et al, 1987b); Murine MXGene-Interferon, Newcastle Disease Virus (Hug et al, 1988); GRP78Gene-A23187 (Resendez et al, 1988); α-2-Macroglobulin-IL-6 (Kunz et al,1989); Vimentin-Serum (Rittling et al, 1989); MHC Class I GeneH-2κb-Interferon (Blanar et al, 1989); HSP70-E1A/SV40 Large T Antigen(Taylor et al, 1989, 1990a, 1990b); Proliferin-Phorbol Ester/TPA(Mordacq et al, 1989); Tumor Necrosis Factor-PMA (Hensel et al, 1989);and Thyroid Stimulating Hormoneα Gene-Thyroid Hormone (Chatterjee et al,1989).

Also contemplated as useful in the present invention are the dectin-1and dectin-2 promoters. Additionally any promoter/enhancer combination(as per the Eukaryotic Promoter Data Base EPDB) could also be used todrive expression of structural genes encoding oligosaccharide processingenzymes, protein folding accessory proteins, selectable marker proteinsor a heterologous protein of interest.

The particular promoter that is employed to control the expression ofpeptide or protein encoding polynucleotide of the invention is notbelieved to be critical, so long as it is capable of expressing thepolynucleotide in a targeted cell, preferably a bacterial cell. Where ahuman cell is targeted, it is preferable to position the polynucleotidecoding region adjacent to and under the control of a promoter that iscapable of being expressed in a human cell. Generally speaking, such apromoter might include either a bacterial, human or viral promoter.

In various embodiments, the human cytomegalovirus (CMV) immediate earlygene promoter, the SV40 early promoter, and the Rous sarcoma virus longterminal repeat can be used to obtain high level expression of a relatedpolynucleotide to this invention. The use of other viral or mammaliancellular or bacterial phage promoters, which are well known in the art,to achieve expression of polynucleotides is contemplated as well.

In embodiments in which a vector is administered to a subject forexpression of the protein, it is contemplated that a desirable promoterfor use with the vector is one that is not down-regulated by cytokinesor one that is strong enough that even if down-regulated, it produces aneffective amount of the protein/polypeptide of the current invention ina subject to elicit an immune response. Non-limiting examples of theseare CMV IE and RSV LTR. In other embodiments, a promoter that isup-regulated in the presence of cytokines is employed. The MHC Ipromoter increases expression in the presence of IFN-γ.

Tissue specific promoters can be used, particularly if expression is incells in which expression of an antigen is desirable, such as dendriticcells or macrophages. The mammalian MHC I and MHC II promoters areexamples of such tissue-specific promoters. 2. Initiation Signals andInternal Ribosome Binding Sites (IRES)

A specific initiation signal also may be required for efficienttranslation of coding sequences. These signals include the ATGinitiation codon or adjacent sequences. Exogenous translational controlsignals, including the ATG initiation codon, may need to be provided.One of ordinary skill in the art would readily be capable of determiningthis and providing the necessary signals. It is well known that theinitiation codon must be “in-frame” with the reading frame of thedesired coding sequence to ensure translation of the entire insert. Theexogenous translational control signals and initiation codons can beeither natural or synthetic and may be operable in bacteria or mammaliancells. The efficiency of expression may be enhanced by the inclusion ofappropriate transcription enhancer elements.

In certain embodiments of the invention, the use of internal ribosomeentry sites (IRES) elements are used to create multigene, orpolycistronic, messages. IRES elements are able to bypass the ribosomescanning model of 5′ methylated Cap dependent translation and begintranslation at internal sites (Pelletier and Sonenberg, 1988). IRESelements from two members of the picornavirus family (polio andencephalomyocarditis) have been described (Pelletier and Sonenberg,1988), as well an IRES from a mammalian message (Macejak and Sarnow,1991). IRES elements can be linked to heterologous open reading frames.Multiple open reading frames can be transcribed together, each separatedby an IRES, creating polycistronic messages. By virtue of the IRESelement, each open reading frame is accessible to ribosomes forefficient translation. Multiple genes can be efficiently expressed usinga single promoter/enhancer to transcribe a single message (see U.S. Pat.Nos. 5,925,565 and 5,935,819, herein incorporated by reference).

2. Multiple Cloning Sites

Vectors can include a multiple cloning site (MCS), which is a nucleicacid region that contains multiple restriction enzyme sites, any ofwhich can be used in conjunction with standard recombinant technology todigest the vector. (See Carbonelli et al, 1999, Levenson et al, 1998,and Cocea, 1997, incorporated herein by reference.) Frequently, a vectoris linearized or fragmented using a restriction enzyme that cuts withinthe MCS to enable exogenous sequences to be ligated to the vector.Techniques involving restriction enzymes and ligation reactions are wellknown to those of skill in the art of recombinant technology.

3. Splicing Sites

Most transcribed eukaryotic RNA molecules will undergo RNA splicing toremove introns from the primary transcripts. If relevant in the contextof vectors of the present invention, vectors containing genomiceukaryotic sequences may require donor and/or acceptor splicing sites toensure proper processing of the transcript for protein expression. (SeeChandler et al, 1997, incorporated herein by reference.)

4. Termination Signals

The vectors or constructs of the present invention will generallycomprise at least one termination signal. A “termination signal” or“terminator” is comprised of the DNA sequences involved in specifictermination of an RNA transcript by an RNA polymerase. Thus, in certainembodiments a termination signal that ends the production of an RNAtranscript is contemplated. A terminator may be necessary in vivo toachieve desirable message levels.

In eukaryotic systems, the terminator region may also comprise specificDNA sequences that permit site-specific cleavage of the new transcriptso as to expose a polyadenylation site. This signals a specializedendogenous polymerase to add a stretch of about 200 A residues (poly A)to the 3′ end of the transcript. RNA molecules modified with this polyAtail appear to more stable and are translated more efficiently. Thus, inother embodiments involving eukaryotes, it is preferred that thatterminator comprises a signal for the cleavage of the RNA, and it ismore preferred that the terminator signal promotes polyadenylation ofthe message.

Terminators contemplated for use in the invention include any knownterminator of transcription described herein or known to one of ordinaryskill in the art, including but not limited to, for example, the bovinegrowth hormone terminator or viral termination sequences, such as theSV40 terminator. In certain embodiments, the termination signal may be alack of transcribable or translatable sequence, such as due to asequence truncation.

5. Polyadenylation Signals

In expression, particularly eukaryotic expression (as is relevant innucleic acid vaccination), one will typically include a polyadenylationsignal to effect proper polyadenylation of the transcript. The nature ofthe polyadenylation signal is not believed to be crucial to thesuccessful practice of the invention, and/or any such sequence may beemployed. Preferred embodiments include the SV40 polyadenylation signaland/or the bovine growth hormone polyadenylation signal, convenientand/or known to function well in various target cells. Polyadenylationmay increase the stability of the transcript or may facilitatecytoplasmic transport.

6. Origins of Replication

In order to propagate a vector in a host cell, it may contain one ormore origins of replication sites (often termed “on”), which is aspecific nucleic acid sequence at which replication is initiated.Alternatively an autonomously replicating sequence (ARS) can be employedif the host cell is yeast.

7. Selectable and Screenable Markers

In certain embodiments of the invention, cells containing a nucleic acidconstruct of the present invention may be identified in vitro or in vivoby encoding a screenable or selectable marker in the expression vector.When transcribed and translated, a marker confers an identifiable changeto the cell permitting easy identification of cells containing theexpression vector. Generally, a selectable marker is one that confers aproperty that allows for selection. A positive selectable marker is onein which the presence of the marker allows for its selection, while anegative selectable marker is one in which its presence prevents itsselection. An example of a positive selectable marker is a drugresistance marker.

Usually the inclusion of a drug selection marker aids in the cloning andidentification of transformants, for example, markers that conferresistance to neomycin, puromycin, hygromycin, DHFR, GPT, zeocin orhistidinol are useful selectable markers. In addition to markersconferring a phenotype that allows for the discrimination oftransformants based on the implementation of conditions, other types ofmarkers including screenable markers such as GFP for colorimetricanalysis. Alternatively, screenable enzymes such as herpes simplex virusthymidine kinase (tk) or chloramphenicol acetyltransferase (CAT) may beutilized. One of skill in the art would also know how to employimmunologic markers that can be used in conjunction with FACS analysis.The marker used is not believed to be important, so long as it iscapable of being expressed simultaneously with the nucleic acid encodinga protein of the invention. Further examples of selectable andscreenable markers are well known to one of skill in the art.

The Transformed Cells of the Invention

Transformed cells of the invention are useful as organisms for producingthe polypeptide of the invention, but also as simple “containers” ofnucleic acids and vectors of the invention.

Certain transformed cells of the invention are capable of replicatingthe nucleic acid fragment defined for option i) of the second aspect ofthe invention. Preferred transformed cells of the invention are capableof expressing the nucleic acid fragment defined for option i).

For recombinant production it is convenient, but not a prerequisite thatthe transformed cell according is prokaryotic, such as a bacterium, butgenerally both prokaryotic cells and eukaryotic cells may be used.

Suitable prokaryotic cells are bacterial cells selected from the groupconsisting of Escherichia (such as E. coli.), Bacillus, (e.g. Bacillussubtilis) Salmonella, and Mycobacterium [preferably non-pathogenic,(e.g. M. bovis BCG)].

Eukaryotic cells can be in the form of yeasts (such as Saccharomycescerevisiae) and protozoans. Alternatively, the transformed eukaryoticcells are derived from a multicellular organism such as a fungus, aninsect cell, a plant cell, or a mammalian cell.

For production purposes, it is advantageous that the transformed cell ofthe invention is is stably transformed by having the nucleic aciddefined above for option i) stably integrated into its genome, and incertain embodiments it is also preferred that the transformed cellsecretes or carries on its surface the polypeptide of the invention,since this facilitates recovery of the polypeptides produced. Aparticular version of this embodiment is one where the transformed cellis a bacterium and secretion of the polypeptide of the invention is intothe periplasmic space.

As noted above, stably transformed cells are preferred—these inter aliaallows that cell lines comprised of transformed cells as defined hereinmay be established—such cell lines are particularly preferred aspects ofthe invention.

Further details on cells and cell lines are presented in the following:

Suitable cells for recombinant nucleic acid expression of the nucleicacid fragments of the present invention are prokaryotes and eukaryotes.Examples of prokaryotic cells include E. coli; members of theStaphylococcus genus, such as S. epidermidis; members of theLactobacillus genus, such as L. plantarum; members of the Lactococcusgenus, such as L. lactis; members of the Bacillus genus, such as B.subtilis; members of the Corynebacterium genus such as C. glutamicum;and members of the Pseudomonas genus such as Ps. fluorescens. Examplesof eukaryotic cells include mammalian cells; insect cells; yeast cellssuch as members of the Saccharomyces genus (e.g. S. cerevisiae), membersof the Pichia genus (e.g. P. pastoris), members of the Hansenula genus(e.g. H. polymorpha), members of the Kluyveromyces genus (e.g. K. lactisor K. fragilis) and members of the Schizosaccharomyces genus (e.g. S.pombe).

Techniques for recombinant gene production, introduction into a cell,and recombinant gene expression are well known in the art. Examples ofsuch techniques are provided in references such as Ausubel, CurrentProtocols in Molecular Biology, John Wiley, 1987-2002, and Sambrook etal., Molecular Cloning, A Laboratory Manual, 2 nd Edition, Cold SpringHarbor Laboratory Press, 1989.

As used herein, the terms “cell,” “cell line,” and “cell culture” may beused interchangeably. All of these terms also include their progeny,which is any and all subsequent generations. It is understood that allprogeny may not be identical due to deliberate or inadvertent mutations.In the context of expressing a heterologous nucleic acid sequence, “hostcell” refers to a prokaryotic or eukaryotic cell, and it includes anytransformable organism that is capable of replicating a vector orexpressing a heterologous gene encoded by a vector. A host cell can, andhas been, used as a recipient for vectors or viruses. A host cell may be“transfected” or “transformed,” which refers to a process by whichexogenous nucleic acid, such as a recombinant protein-encoding sequence,is transferred or introduced into the host cell. A transformed cellincludes the primary subject cell and its progeny.

Host cells may be derived from prokaryotes or eukaryotes, includingbacteria, yeast cells, insect cells, and mammalian cells for replicationof the vector or expression of part or all of the nucleic acidsequence(s). Numerous cell lines and cultures are available for use as ahost cell, and they can be obtained through the American Type CultureCollection (ATCC), which is an organization that serves as an archivefor living cultures and genetic materials or from other depositoryinstitutions such as Deutsche Sammlung vor Micrroorganismen andZellkulturen (DSM). An appropriate host can be determined by one ofskill in the art based on the vector backbone and the desired result. Aplasmid or cosmid, for example, can be introduced into a prokaryote hostcell for replication of many vectors or expression of encoded proteins.Bacterial cells used as host cells for vector replication and/orexpression include Staphylococcus strains, DH5α, JMl 09, and KC8, aswell as a number of commercially available bacterial hosts such as SURE®Competent Cells and SOLOP ACK™ Gold Cells (STRATAGENE®, La Jolla,Calif.). Alternatively, bacterial cells such as (E. coli LE392) could beused as host cells for phage viruses. Appropriate yeast cells includeSaccharomyces cerevisiae, Saccharomyces pombe, and Pichia pastoris.

Examples of eukaryotic host cells for replication and/or expression of avector include HeLa, NIH3T3, Jurkat, 293, Cos, CHO, Saos, and PC12. Manyhost cells from various cell types and organisms are available and wouldbe known to one of skill in the art. Similarly, a viral vector may beused in conjunction with either a eukaryotic or prokaryotic host cell,particularly one that is permissive for replication or expression of thevector.

Some vectors may employ control sequences that allow it to be replicatedand/or expressed in both prokaryotic and eukaryotic cells. One of skillin the art would further understand the conditions under which toincubate all of the above described host cells to maintain them and topermit replication of a vector. Also understood and known are techniquesand conditions that would allow large-scale production of vectors, aswell as production of the nucleic acids encoded by vectors and theircognate polypeptides, proteins, or peptides.

Expression Systems

Numerous expression systems exist that comprise at least a part or allof the compositions discussed above. Prokaryote- and/or eukaryote-basedsystems can be employed for use with the present invention to producenucleic acid sequences, or their cognate polypeptides, proteins andpeptides. Many such systems are commercially and widely available.

The insect cell/baculovirus system can produce a high level of proteinexpression of a heterologous nucleic acid segment, such as described inU.S. Pat. Nos. 5,871,986, 4,879,236, both herein incorporated byreference, and which can be bought, for example, under the name MAXBACC®2.0 from INVITROGEN® and BACPACK™ Baculovirus expression system fromCLONTECH®.

In addition to the disclosed expression systems of the invention, otherexamples of expression systems include STRATAGENE®'s COMPLETE CONTROL™Inducible Mammalian Expression System, which involves a syntheticecdysone-inducible receptor, or its pET Expression System, an E. coliexpression system. Another example of an inducible expression system isavailable from INVITROGEN®, which carries the T-REX™(tetracycline-regulated expression) System, an inducible mammalianexpression system that uses the full-length CMV promoter. INVITROGEN®also provides a yeast expression system called the Pichia methanolicaExpression System, which is designed for high-level production ofrecombinant proteins in the methylotrophic yeast (Pichia methanolica).One of skill in the art would know how to express a vector, such as anexpression construct, to produce a nucleic acid sequence or its cognatepolypeptide, protein, or peptide.

Amplification of Nucleic Acids

Nucleic acids used as a template for amplification may be isolated fromcells, tissues or other samples according to standard methodologies(Sambrook et al, 2001). In certain embodiments, analysis is performed onwhole cell or tissue homogenates or biological fluid samples withoutsubstantial purification of the template nucleic acid. The nucleic acidmay be genomic DNA or fractionated or whole cell RNA. Where RNA is used,it may be desired to first convert the RNA to a complementary DNA.

The term “primer,” as used herein, is meant to encompass any nucleicacid that is capable of priming the synthesis of a nascent nucleic acidin a template-dependent process. Typically, primers are oligonucleotidesfrom ten to twenty and/or thirty base pairs in length, but longersequences can be employed. Primers may be provided in double-strandedand/or single-stranded form, although the single-stranded form ispreferred.

Pairs of primers designed to selectively hybridize to nucleic acidscorresponding to sequences of genes identified herein are contacted withthe template nucleic acid under conditions that permit selectivehybridization. Depending upon the desired application, high stringencyhybridization conditions may be selected that will only allowhybridization to sequences that are completely complementary to theprimers. In other embodiments, hybridization may occur under reducedstringency to allow for amplification of nucleic acids containing one ormore mismatches with the primer sequences. Once hybridized, thetemplate-primer complex is contacted with one or more enzymes thatfacilitate template-dependent nucleic acid synthesis. Multiple rounds ofamplification, also referred to as “cycles,” are conducted until asufficient amount of amplification product is produced.

The amplification product may be detected or quantified. In certainapplications, the detection may be performed by visual means.Alternatively, the detection may involve indirect identification of theproduct via chemiluminescence, radioactive scintigraphy of incorporatedradiolabel or fluorescent label or even via a system using electricaland/or thermal impulse signals (Bellus, 1994).

A number of template dependent processes are available to amplify theoligonucleotide sequences present in a given template sample. One of thebest known amplification methods is the polymerase chain reaction(referred to as PCR™) which is described in detail in U.S. Pat. Nos.4,683,195, 4,683,202 and 4,800,159, and in Innis et al., 1988, each ofwhich is incorporated herein by reference in their entirety.

Alternative methods for amplification of target nucleic acid sequencesthat may be used in the practice of the present invention are disclosedin U.S. Pat. Nos. 5,843,650, 5,846,709, 5,846,783, 5,849,546, 5,849,497,5,849,547, 5,858,652, 5,866,366, 5,916,776, 5,922,574, 5,928,905,5,928,906, 5,932,451, 5,935,825, 5,939,291 and 5,942,391, GB ApplicationNo. 2 202 328, and in PCT Application No. PCT/US89/01025, each of whichis incorporated herein by reference in its entirety.

Methods of Gene Transfer

Suitable methods for nucleic acid delivery to effect expression ofcompositions of the present invention are believed to include virtuallyany method by which a nucleic acid (e.g., DNA, including viral andnonviral vectors) can be introduced into a cell, a tissue or anorganism, as described herein or as would be known to one of ordinaryskill in the art. Such methods include, but are not limited to, directdelivery of DNA such as by injection (U.S. Pat. Nos. 5,994,624,5,981,274, 5,945,100, 5,780,448, 5,736,524, 5,702,932, 5,656,610,5,589,466 and 5,580,859, each incorporated herein by reference),including microinjection (Harland and Weintraub, 1985; U.S. Pat. No.5,789,215, incorporated herein by reference); by electroporation (U.S.Pat. No. 5,384,253, incorporated herein by reference); by calciumphosphate precipitation (Graham and Van Der Eb, 1973; Chen and Okayama,1987; Rippe et al., 1990); by using DEAE dextran followed bypolyethylene glycol (Gopal, 1985); by direct sonic loading (Fechheimeret al, 1987); by liposome mediated transfection (Nicolau and Sene, 1982;Fraley et al, 1979; Nicolau et al, 1987; Wong et al, 1980; Kaneda et al,1989; Kato et al, 1991); by microprojectile bombardment (PCT ApplicationNos. WO 94/09699 and 95/06128; U.S. Pat. Nos. 5,610,042; 5,322,7835,563,055, 5,550,318, 5,538,877 and 5,538,880, and each incorporatedherein by reference); by agitation with silicon carbide fibers (Kaeppleret al, 1990; U.S. Pat.

Nos. 4,684,611 and 4,952,500, each incorporatedherein by reference); by desiccation/inhibition mediated DNA uptake(Potrykus et al, 1985). Through the application of techniques such asthese, organelle(s), cell(s), tissue(s) or organism(s) may be stably ortransiently transformed.

The Antibodies of the Invention—and their Production/Isolation

Antibodies directed against the proteins of the invention are useful foraffinity chromatography, immunoassays, and fordistinguishing/identifying staphylococcus proteins as well as forpassive immunisation and therapy.

Antibodies to the proteins of the invention, both polyclonal andmonoclonal, may be prepared by conventional methods. In general, theprotein is first used to immunize a suitable animal, preferably a mouse,rat, rabbit or goat. Rabbits and goats are preferred for the preparationof polyclonal sera due to the volume of serum obtainable, and theavailability of labeled anti-rabbit and anti-goat antibodies.Immunization is generally performed by mixing or emulsifying the proteinin saline, preferably in an adjuvant such as Freund's complete adjuvant,and injecting the mixture or emulsion parenterally (generallysubcutaneously or intramuscularly). A dose of 50-200 μg/injection istypically sufficient. Immunization is generally boosted 2-6 weeks laterwith one or more injections of the protein in saline, preferably usingFreund's incomplete adjuvant. One may alternatively generate antibodiesby in vitro immunization using methods known in the art, which for thepurposes of this invention is considered equivalent to in vivoimmunization. Polyclonal antiserum is obtained by bleeding the immunizedanimal into a glass or plastic container, incubating the blood at 25 Cfor one hour, followed by incubating at 4 C for 2-18 hours. The serum isrecovered by centrifugation (eg. 1,000 g for 10 minutes). About 20-50 mlper bleed may be obtained from rabbits.

Monoclonal antibodies are prepared using the standard method of Kohler &Milstein [Nature (1975) 256: 495-96], or a modification thereof.Typically, a mouse or rat is immunized as described above. However,rather than bleeding the animal to extract serum, the spleen (andoptionally several large lymph nodes) is removed and dissociated intosingle cells. If desired, the spleen cells may be screened (afterremoval of nonspecifically adherent cells) by applying a cell suspensionto a plate or well coated with the protein antigen. B-cells expressingmembrane-bound immunoglobulin specific for the antigen bind to theplate, and are not rinsed away with the rest of the suspension.Resulting B-cells, or all dissociated spleen cells, are then induced tofuse with myeloma cells to form hybridomas, and are cultured in aselective 1 aedium (elg. hypexanthine, aminopterin, thymidinemedium,“HAT”). The resulting hybridomas are plated by limiting dilution,and are assayed for production of antibodies, which bind specifically tothe immunizing antigen (and which do not bind to unrelated antigens).The selected MAb-secreting hybridomas are then cultured either in vitro(eg. in tissue culture bottles or hollow fiber reactors), or in vivo (asascites in mice).

If desired, the antibodies (whether polyclonal or monoclonal) may belabeled using conventional techniques. Suitable labels includefluorophores, chromophores, radioactive atoms (particularly 32p and125I), electron-dense reagents, enzymes, and ligands having specificbinding partners. Enzymes are typically detected by their activity. Forexample, horseradish peroxidase is usually detected by its ability toconvert 3,3′, 5,5′-tetramethylbenzidine (TMB) to a blue pigment,quantifiable with a spectrophotometer. “Specific binding partner” refersto a protein capable of binding a ligand molecule with high specificity,as for example in the case of an antigen and a monoclonal antibodyspecific therefor. Other specific binding partners include biotin andavidin or streptavidin, IgG and protein A, and the numerousreceptor-ligand couples known in the art. It should be understood thatthe above description is not meant to categorize the various labels intodistinct classes, as the same label may serve in several differentmodes. For example, 1151 may serve as a radioactive label or as anelectron-dense reagent. HRP may serve as enzyme or as antigen for a MAb.Further, one may combine various labels for desired effect. For example,MAbs and avidin also require labels in the practice of this invention:thus, one might label a MAb with biotin, and detect its presence withavidin labeled with, 125I, or with an anti-biotin MAb labeled with HRP.Other permutations and possibilities will be readily apparent to thoseof ordinary skill in the art, and are considered as equivalents withinthe scope of the instant invention.

According to the invention, the isolated monoclonal antibody or antibodyanalogue is preferably a monoclonal antibody selected from amulti-domain antibody such as a murine antibody, a chimeric antibodysuch as a humanized antibody, a fully human antibody, and single-domainantibody of a llama or a camel, or which is an antibody analogueselected from a fragment of an antibody such as an Fab or an F(ab′)₂, anscFV; cf. also the definition of the term “antibody” presented above.

Compositions of the Invention; Vaccines

Pharmaceutical compositions, in particular vaccines, according to theinvention may either be prophylactic (ie. to prevent infection) ortherapeutic (ie, to treat disease after infection).

Such vaccines comprise immunising antigen(s), immunogen(s),polypeptide(s), protein(s) or nucleic acid(s), usually in combinationwith “pharmaceutically acceptable carriers”, which include any carrierthat does not itself induce the production of antibodies harmful to theindividual receiving the composition. Suitable carriers are typicallylarge, slowly metabolized macromolecules such as proteins,polysaccharides, polylactic acids, polyglycolic acids, polymeric aminoacids, amino acid copolymers, lipid aggregates (such as oil droplets orliposomes), and inactive virus particles.

Such carriers are well known to those of ordinary skill in the art.Additionally, these carriers may function as immunostimulating agents(“adjuvants”). Furthermore, the antigen or immunogen may be conjugatedto a bacterial toxoid, such as a toxoid from diphtheria, tetanus,cholera, H. pylori, etc. pathogen, cf. the description of immunogeniccarriers supra.

The pharmaceutical compositions of the invention thus typically containan immunological adjuvant, which is commonly an aluminium based adjuvantor one of the other adjuvants described in the following:

Preferred adjuvants to enhance effectiveness of the composition include,but are not limited to: (1) aluminum salts (alum), such as aluminumhydroxide, aluminum phosphate, aluminum sulfate, etc; (2) oil-in-wateremulsion formulations (with or without other specific immunostimulatingagents such as muramyl peptides (see below) or bacterial cell wallcomponents), such as for example (a) MF59 (WO 90/14837; Chapter 10 inVaccine design: the subunit and adjuvant approach, eds. Powell & Newman,Plenum Press 1995), containing 5% Squalene, 0.5% Tween 80, and 0.5% Span85 (optionally containing various amounts of MTP-PE (see below),although not required) formulated into submicron particles using amicrofluidizer such as Model 110Y microfluidizer (Microfluidics, Newton,Mass.), (b) SAF, containing 10% Squalane, 0.4% Tween 80, 5%pluronic-blocked polymer L121, and thr-MDP (see below) eithermicrofluidized into a submicron emulsion or vortexed to generate alarger particle size emulsion, and (c) Ribi adjuvant system (RAS), (RibiImmunochem, Hamilton, Mont.) containing 2% Squalene, 0.2% Tween 80, andone or more bacterial cell wall components from the group consisting ofmonophosphoryl lipid A (MPL), trehalose dimycolate (TDM), and cell wallskeleton (CWS), preferably MPL+CWS (Detox™); (3) saponin adjuvants suchas Stimulon™ (Cambridge Bioscience, Worcester, Mass.) may be used orparticles generated therefrom such as ISCOMs (immunostimulatingcomplexes); (4) Complete Freund's Adjuvant (CFA) and Incomplete Freund'sAdjuvant (IFA); (5) cytokines, such as interleukins (eg. IL-1, IL-2,IL-4, IL-5, IL-6, IL-7, IL-12, etc.), interferons (eg. gammainterferon), macrophage colony stimulating factor (M-CSF), tumornecrosis factor (TNF), etc.; and (6) other substances that act asimmunostimulating agents to enhance the effectiveness of thecomposition. Alum and MF59™ adjuvants are preferred.

As mentioned above, muramyl peptides include, but are not limited to,N-acetyl-muramyl-L-threonyl-D-isoglutamine (thr-MDP),N-acetyl-normuramyl-L-alanyl-D-isoglutamine (nor-MDP),N-acetylmuramyl-L-alanyl-D-isoglutaminyl-L-alanine-2″-2′-dipalmitoyl-sn-glycero-3-hydroxyphosphoryloxy)-ethylamine(MTP-PE), etc.

The immunogenic compositions (eg. the immunising antigen or immunogen orpolypeptide or protein or nucleic acid, pharmaceutically acceptablecarrier, and adjuvant) typically will contain diluents, such as water,saline, glycerol, ethanol, etc. Additionally, auxiliary substances, suchas wetting or emulsifying agents, pH buffering substances, and the like,may be present in such vehicles.

Typically, the immunogenic compositions are prepared as injectables,either as liquid solutions or suspensions; solid forms suitable forsolution in, or suspension in, liquid vehicles prior to injection mayalso be prepared. The preparation also may be emulsified or encapsulatedin liposomes for enhanced adjuvant effect, as discussed above underpharmaceutically acceptable carriers.

Immunogenic compositions used as vaccines comprise an immunologicallyeffective amount of the antigenic or immunogenic polypeptides, as wellas any other of the above-mentioned components, as needed. By“immunologically effective amount”, it is meant that the administrationof that amount to an individual, either in a single dose or as part of aseries, is effective for treatment or prevention. This amount variesdepending upon the health and physical condition of the individual to betreated, the taxonomic group of individual to be treated (eg. non-humanprimate, primate, etc.), the capacity of the individual's immune systemto synthesize antibodies or generally mount an immune response, thedegree of protection desired, the formulation of the vaccine, thetreating doctor's assessment of the medical situation, and otherrelevant factors. It is expected that the amount will fall in arelatively broad range that can be determined through routine trials.However, for the purposes of protein vaccination, the amountadministered per immunization is typically in the range between 0.5 μgand 500 mg (however, often not higher than 5,000 μg), and very often inthe range between 10 and 200 μg.

The immunogenic compositions are conventionally administeredparenterally, eg, by injection, either subcutaneously, intramuscularly,or transdermally/transcutaneously (eg. WO98/20734). Additionalformulations suitable for other modes of administration include oral andpulmonary formulations, suppositories, and transdermal applications. Inthe case of nucleic acid vaccination, also the intravenous orintraarterial routes may be applicable.

Dosage treatment may be a single dose schedule or a multiple doseschedule. The vaccine may be administered in conjunction with otherimmunoregulatory agents.

As an alternative to protein-based vaccines, DNA vaccination (alsotermed nucleic acid vaccination or gene vaccination) may be used [eg.Robinson & Torres (1997) Seminars in Immunol 9: 271-283; Donnelly et al.(1997) Annu Rev Immunol 15: 617-648; later herein].

Treatment Methods of the Invention

The method of the sixth aspect of the invention generally relates toinduction of immunity and as such also entails method that relate totreatment, prophylaxis and amelioration of disease.

When immunization methods entail that a polypeptide of the invention ora composition comprising such a polypeptide is administered the animal(e.g. the human) typically receives between 0.5 and 5,000 μg of thepolypeptide of the invention per administration.

In preferred embodiments of the sixth aspect, the immunization schemeincludes that the animal (e.g. the human) receives a primingadministration and one or more booster administrations.

Preferred embodiments of the 6^(th) aspect of the invention comprisethat the administration is for the purpose of inducing protectiveimmunity against C. jejuni. In this embodiment it is particularlypreferred that the protective immunity is effective in reducing the riskof attracting infection with C. jejuni or is effective in treating orameliorating infection with C. jejuni.

As mentioned herein, the preferred vaccines of the invention inducehumoral immunity, so it is preferred that the administration is for thepurpose of inducing antibodies specific for C. jejuni and wherein saidantibodies or B-lymphocytes producing said antibodies are subsequentlyrecovered from the animal.

But, as also mentioned the method of the 6^(th) aspect may also beuseful in antibody production, so in other embodiments theadministration is for the purpose of inducing antibodies specific for C.jejuni and wherein B-lymphocytes producing said antibodies aresubsequently recovered from the animal and used for preparation ofmonoclonal antibodies.

Pharmaceutical compositions can as mentioned above comprisepolypeptides, antibodies, or nucleic acids of the invention. Thepharmaceutical compositions will comprise a therapeutically effectiveamount thereof.

The term “therapeutically effective amount” or “prophylacticallyeffective amount” as used herein refers to an amount of a therapeuticagent to treat, ameliorate, or prevent a desired disease or condition,or to exhibit a detectable therapeutic or preventative effect. Theeffect can be detected by, for example, chemical markers or antigenlevels. Therapeutic effects also include reduction in physical symptoms,such as decreased body temperature. The precise effective amount for asubject will depend upon the subject's size and health, the nature andextent of the condition, and the therapeutics or combination oftherapeutics selected for administration. Thus, it is not useful tospecify an exact effective amount in advance. Reference is however madeto the ranges for dosages of immunologically effective amounts ofpolypeptides, cf. above.

However, the effective amount for a given situation can be determined byroutine experimentation and is within the judgement of the clinician.

For purposes of the present invention, an effective dose will be fromabout 0.01 mg/kg to 50 mg/kg or 0.05 mg/kg to about 10 mg/kg of the DNAconstructs in the individual to which it is administered.

A pharmaceutical composition can also contain a pharmaceuticallyacceptable carrier. The term “pharmaceutically acceptable carrier”refers to a carrier for administration of a therapeutic agent, such asantibodies or a polypeptide, genes, and other therapeutic agents. Theterm refers to any pharmaceutical carrier that does not itself inducethe production of antibodies harmful to the individual receiving thecomposition, and which may be administered without undue toxicity.Suitable carriers may be large, slowly metabolized macromolecules suchas proteins, polysaccharides, polylactic acids, polyglycolic acids,polymeric amino acids, amino acid copolymers, and inactive virusparticles. Such carriers are well known to those of ordinary skill inthe art.

Pharmaceutically acceptable salts can be used therein, for example,mineral acid salts such as hydrochlorides, hydrobromides, phosphates,sulfates, and the like; and the salts of organic acids such as acetates,propionates, malonates, benzoates, and the like. A thorough discussionof pharmaceutically acceptable excipients is available in Remington'sPharmaceutical Sciences (Mack Pub. Co., N. J. 1991).

Pharmaceutically acceptable carriers in therapeutic compositions maycontain liquids such as water, saline, glycerol and ethanol.Additionally, auxiliary substances, such as wetting or emulsifyingagents, pH buffering substances, and the like, may be present in suchvehicles. Typically, the therapeutic compositions are prepared asinjectables, either as liquid solutions or suspensions; solid formssuitable for solution in, or suspension in, liquid vehicles prior toinjection may also be prepared. Liposomes are included within thedefinition of a pharmaceutically acceptable carrier.

As is apparent from the claim, the invention also relates to relatedembodiments to the treatment and prophylaxis disclosed herein: theinvention also includes embodiments where

the polypeptide of the invention is for use as a pharmaceutical, inparticular for use as a pharmaceutical in the treatment, prophylaxis oramelioration of infection with C. jejuni;

EXAMPLES Material and Methods Bacterial Strains and Plasmid

The bacterial strains used in this study included E. coli SURE(Stratagene) and E. coli BL21 (DE3) (Stratagene) and the plasmid waspTLJ03. Strains and plasmid originates from a NCTC 11168 C. jejuni ORFlibrary (Parrish et al., 2004) available from Geneservice. Theexpression clone set comprises >1,600 C. jejuni ORF's and the expressionvector pTLJ03 generates N-terminal GST-His-tagged fusion proteins.

Strains were grown in LB media or the expression media MagicMedia(Invitrogen) at 37° C. pTLJ03 containing strains were grown in mediacontaining 50 μg/mL ampicillin unless otherwise specified. C. jejuni11168H is a stable motile variant of the reference strain C. jejuni NCTC11168; its preparation is described infra in the section headed“recombinant DNA techniques”. C. jejuni strains (NCTC 11168 and 11168H)were grown at 37° C. microaerophilic on blood plates (BaseII and 5%blood) in BHI broth or biphasic (blood plates and BHI broth) withantibiotic when needed (30 μg/mL kanamycin or/and 50 μg/mLstreptomycin).

Expression Library

The library was originally created in E. coli SURE for optimal storage.This strain does not contain the T7 polymerase and for that reason thelibrary was transformed to the E. coli BL21 (DE3) expression strain. Theclones were grown separately overnight in microtiter plates in 200 μl LBmedia containing ampicillin and subsequently the plasmids were purifiedas a pool and transformed to the chemocompetent E. coli BL21 (DE3)strain. This revealed an expression library consisting of 2304 clones(24 microtiter plates).

Immunoblot Assay

Individual clones were grown 16-20 hrs in microtiter plates inMagicMedia for optimal expression. 2 μl of the culture was spotted onnitrocellulose membranes. The membranes were blocked in blocking buffer30 min., washed in PBS Tween and then incubated in primary antibody(1:1000) at 4° C. for 16-20 hrs. The membranes were then washed in PBSTween and incubated in secondary antibody (Polyclonal goat anti-rabbitimmunoglobulins/HRP, Dako) for 1 hr. The reaction was visualised bychemoluminescence (chemoluminescent substrate, Invitrogen). The primaryantibody was raised in rabbit immunised with a boiled-treated (100° C.for 1 h) C. jejuni Penner serotype 2 originally isolated from a humanpatient. Rabbit serum from immunisations with the Penner serotype 2 waschosen since it corresponds to the serotype used for creating thecommercial library (NCTC 11168). The serum was preincubated with E. coliBL21 (DE3) before use to minimise background reaction. To verify thatthe antigens also reacted against human serum, a dot blot with 10selected clones expressing antigens and serum isolated from a patientinfected with C. jejuni Penner serotype 2 (Strid M A et al. 2001,“Antibody responses to Campylobacter infections determined by anenzyme-linked immunosorbent assay: 2-year follow-up study of 210patients”, Clin. Diag. Lab. Immunol. 183:2553-9.) was carried out asdescribed above.

Clone Sequencing

Plasmid DNA was isolated from 100 ml E. coli BL21 (DE3) cultures usingMidiPrep (Qiagen). Sequencing was conducted by Macrogen Inc. and theprimer 5′ GCT ATC CCA CAA ATT GAT AA 3′ (SEQ ID NO: 91).

Recombinant DNA Techniques

C. jejuni 11168H knock-out mutants were kindly provided by Brendan Wrenfrom the London School of Hygiene and Tropical Medicine, University ofLondon. Mutants were constructed via insertion of the Km cassette intounique sites present in pUC18-based recombinant plasmids containingrandom 1-kb fragments from the C. jejuni NCTC 11168 genome library(Garenaux A et al. 2008, “Role of the Cj1371 periplasmic protein and theCj0355c two-component regulator in the Campylobacter jejuni NCTC 11168response to oxidative stress caused by paraquat”, Res Microbiol. 159:718-26 and Parkhill J et al. 2000, “The genome sequence of thefood-borne pathogen Campylobacter jejuni reveals hypervariablesequences”, Nature 10; 403(6770):665-8). The 11168H knock out mutantprovided for this study is: Cj0034c. Subsequently the gene knock-outswere transferred from the C. jejuni 11168H strain to the C. jejuni 11168strain to restore motility and spiral morfology. Natural transformationwas performed as described previously (Wang Y and Taylor D E 1990,“Natural transformation in Campylobacter species”, J Bacteriol. 172:949-55) with some modifications. C. jejuni cultures grown overnight onBHI agar plates were collected and resuspended in 12 ml BHI broth toOD₆₀₀ of 0.001. Bacterial suspensions in three dilutions weretransferred to sterilized Petri dishes, incubated at 37° C. with noshaking under micro aerobic conditions over night. 200 μg cultures withOD₆₀₀ 0.2-0.3 were transferred to sterilized tube with 1 ml BHI andincubated at 37° C. with shaking under micro aerobic conditions 2 h.Then 10 ng of genomic DNA, purified with Qiagen blood and tissue kit, ofthe mutants, was added each tube. After additional incubation for 3 h,bacterial cultures were serially diluted and plated on BaseII agarplates with antibiotics (50 mg/l kanamycin). The agar plates wereincubated at 37° C. under microaerobic conditions 3 days. The mutantswere checked for curved shape and motility before tested in assays.

INT407 Adhesion Assay

INT407 cells (representing intestinal cell line) were grown in MEM(+glutamax) media (Invitrogen) added 25 μg/ml gentamycin and 10% heatinactivated fetal bovine serum in 5% CO₂. Cells were seeded at 2.5×10⁵prwell in 24 well plates, incubated overnight and checked for 100%confluent monolayer. The E. coli clones were grown overnight inMagicMedia broth at 37° C. and C. jejuni on blood agar platesmicroaerophilic at 37° C. Immediately before assay, the OD₆₀₀ of thebacteria was adjusted to 1 in PBS and 1 ml bacteria culture was addedthe INT407 cells and cells were incubated with bacteria for 2 hours at37° C., then resuspended and diluted in PBS and spotted on agar plateswith appropriate antibiotics.

Electron Microscopy

To investigate, whether the C. jejuni mutant strain differedmorphologically from the wild type strain, a transmission electronmicroscopy analysis was conducted. Initially, the bacterial cultureswere fixated in 1% glutaraldehyde (EMS, Hatfield, USA) for 30 minutes.To improve the adhesion of the bacteria, formvar coated 400-mesh coppergrids were treated for 5 minutes with alcian blue (Sigma-Aldrich). Thealcian blue treated grids were placed on top of cultures of C. jejuniNCTC11168 and C. jejuni NCTC11168L0034 (Cj0034c), respectively, andafter 5 minutes of incubation, most of the suspensions were removed fromthe grids with filter paper and the grids were stained for 30 secondswith phosphotungstic acid (BDH Chemicals). The grids were allowed toair-dry, and then they were viewed in a Morgagni 268D transmissionelectron microscope, and pictures were taken using a Mega-view IIIdigital camera.

Motility Assay

A motility assay was carried out to ensure no altered motility for the11168L0034 mutant. 0.25% soft agar plates were supplied with 1 μlbacterial culture (OD₆₀₀ adjusted to 0.1) in the middle of the plate anddiameter was measured over a time period.

Serum Resistance Assay

Serum sensitivity assays were performed by modification of the method ofBlaser at al (Blaser M J et al. 1985, “Susceptibility of Campylobacterisolates to the bactericidal activity of human serum”, J Infect Dis.151: 227-235.) C. jejuni strains were grown overnight in Brucellabiphasic cultures at 37° C., washed in PBS, pH 7.4, and adjusted to aconcentration of 10³ CFU/ml. C. jejuni cells (10-μl aliquots) wereincubated in 240-μl pools of whole human blood (venous blood), humanserum (whole blood incubated at 25° C. 30 min, centrifuged 1000×g 10 minat 4° C. and supernatant isolated) and heat inactivated human serum (56°C. for 30 min) respectively for 30, 60, 90 and 120 min. Following theincubation period, CFU was enumerated on BHI agar.

Biofilm and Autoagglutination

Cell-to-cell autoagglutination was assayed in PBS as described by Misawaand Blaser (Misawa N and Blaser M J 2000, “Detection andcharacterization of autoagglutination activity by Campylobacter jejuni”,Infect. Immun. 68: 6168-6175.)

Biofilm assay was made in 50 ml centrifuge tubes containing 25 mlinoculated Brucella broth with NCTC 11168 and the knock out mutants inCj0034c. A glass slide was added each tube and incubated micro aerobicfor 48 h. Then the slides were stained with crystal violet and biofilmformation visualised.

Predictions of Protein Localization

Prediction of protein localization and amount of transmembrane helixeswas made by TMHMM 2.0 server (Moller S et al. 2001, “Evaluation ofmethods for the prediction of membrane spanning regions”,Bioinformatics, 17: 646-653).

The SignalP 3.0 server predicts the presence and location of signalpeptide cleavage sites in amino acid sequences. The method incorporatesa prediction of cleavage sites and a signal peptide/non-signal peptideprediction based on a combination of several artificial neural networksand hidden Markov models. The LipoP 1.0 server produces predictions oflipoproteins and discriminates between lipoprotein signal peptides,other signal peptides and N-terminal membrane helices in Gram-negativebacteria (Juncker A S et al. 2003, “Prediction of lipoprotein signalpeptides in Gram-negative bacteria”, Protein Sci. 12:1652-62).

Protein Purification

His-tag purification was made with the already GST-His-taggedconstructed vector from Geneservice. An overnight pre-culture of E. coliBL21(DE3) containing the vectors was 50-fold diluted to inoculate 1000ml LB medium containing appropriate antibiotics. The cultures wereincubated with shaking at 37° C. to an OD₆₀₀ of 0.5, then induced with10 mM IPTG and incubated with shaking for 16 hours at 30° C. Afterinduction, cells were lysed on ice in 20 ml lysis buffer (50 mM NaH₂PO₄,300 mM NaCl, 10 mM imidazole 10% glycerol) by addition of 1 mg/mllysozyme followed by sonication. Lysates were cleared by centrifugationat 15,000×g for 30 min. Proteins were purified by nickel affinitychromatography using the Ni-NTA resin (Qiagen) equilibrated with lysisbuffer and eluted with 250 mM imidazole. Eluted proteins wereconcentrated and dialyzed against 25 mM HEPES pH 7.5, 50 mMNaCl, 10%glycerol.

Mouse Vaccination and Challenge Studies

To study ability of the proteins to protection against infection,immunization of mice were carried out. Cj0404 (SEQ ID NO: 13) was testedtogether with other putative vaccine candidates for its ability toprotect against C. jejuni infection. Mice (10 in each group) wereimmunized with 5 μg/dose, except one with 1.6 μg/dose (Cj1371c), alongwith adjuvant (GNE, Intervet, NL). Four weeks later, the mice (Balb/cfor colonization and CH3/HeN for invasion) were treated for three dayswith streptomycin (5 g/l in drinking water) and challenged orally oneday later with C. jejuni 81116 (6×10⁵ CFU, colonization study) and72Dz/92 (5×10⁷ CFU, invasion study) respectively. Balb/c mice 6-8 weeks(female) were used in groups of three. One fresh faecal dropping wascollected and weighted from each animal and dilutions were made in orderto determine CFU/gram faeces. Faecal samples were collected from theBalb/c mice regularly in 23 days. Necropsy was prepared one week afterchallenge of the CH3/HeN mice, spleen and liver were collected andCFU/organ were detected.

Results

Identification of C. jejuni Antigens

With the aim of identifying immuno-reactive C. jejuni proteins plasmidDNA was isolated from a pooled mixture of commercial library clonesestablished by Parrish et al (Parrish J R et al. 2004, “High-throughputcloning of Campylobacter jejuni ORfs by in vivo recombination inEscherichia coli”, J Proteome Res. 3: 582-6.) with C. jejuni NCTC11168ORFs in the plasmid pTLJO3 (Parrish J R et al. 2004). Plasmid DNA wastransformed into E. coli BL21 to allow expression from the T7 promoter.The resulting transformants were individually spotted on anitrocellulose membrane and reacted with serum isolated from a rabbitinfected with a C. jejuni human clinical isolate (serotype 2). Thescreening revealed several immunogenic E. coli clones that selectivelyreacted with the serum. Inserts in plasmids isolated from thetransformants that repeatedly proved as most immunogenic were selectedfor sequencing and from a total of 2304 clones, 52 inserts weresequenced representing 25 genes encoding potential antigens. Theidentified C. jejuni genes were classified according to their predictedfunction.

To confirm that the identified antigens also are functional in humans wereacted 10 of the 25 clones (Cj0034, Cj0203, Cj0404 (SEQ ID NO: 13),Cj0525c, Cj0645, Cj0917c, Cj1094c, Cj1371, Cj1382c, Cj1632c) with humanantiserum obtained from a patient infected with a C. jejuni Pennerserotype 2 and found in all cases a positive reaction. This resultsupports that the antigens reacting with the mouse antiserum also areantigens in humans.

Prediction of Protein Localization

Prediction of localization of the proteins and amount of transmembranehelixes was made: 14 out of 25 proteins are predicted to contain one ormore membrane helixes, two of them further with a signal peptide. Otherten of the proteins are predicted to be located externally, where threeof them harbor a signal peptide. None of the proteins were predicted tocontain a lipoprotein signal peptidase.

Several Antigens Support Host Cell Adhesion

Adhesion of C. jejuni to host cells forms the first important step inthe infection process. With the aim of addressing whether the identifiedantigens contribute to host cell invasion a selection of 10 E. coliclones expressing C. jejuni antigens were investigated for their abilityto adhere to the intestinal epithelial cell line, INT407. Interestingly,expression of three of the C. jejuni antigens enhanced the ability of E.coli BL21 to adhere to INT407 cells, Cj0034c, Cj0404 (SEQ ID NO: 13) andCj1371. Subsequently, gene-specific C. jejuni mutations were constructedin the corresponding genes, and the resulting mutants were examined inthe same cell adhesion assay. While the absence of Cj0404 and Cj1371 didnot affect the ability of C. jejuni to adhere to INT407 cells,inactivation of Cj0034 dramatically reduced adhesion suggesting thatCj0034 may contribute to establishment of C. jejuni in host organisms.

Further characterization of the Cj0034 mutant C. jejuni strain revealed,that the mutation does not result in major structural changes of thebacterial cell morphology as visualized by electron microscopy. Also,the inactivation of Cj0034 did not influence serum resistance, motility,autoagglutination and biofilm formation, when compared to wild typestrain.

Antigens as Vaccine Candidates

Five identified antigens were selected to test as vaccine candidates intwo Campylobacter oral challenge mouse models; one in C3H/HeN mice inwhich invasion in liver and spleen was measured and the other in Balb/cmice in which shedding faecal was determined. The challenge study showeda reduced invasion into spleen and liver for at least two of theproteins; Cj0525c and Cj0404 (SEQ ID NO: 13). No decreased colonizationfor any of the proteins was observed.

Further Examples C. jejuni Antigen Expression

30 genes encoding potentially antigenic C. jejuni proteins wereidentified and checked in NCBI and presence in the clone library. Of the30 suggested gene sequences, 19 were commercially available andpurchased from Life Sciences. All 19 were used for cloning in expressionplasmid (with his-tag) and transformation into the expression strain E.coli BL21. Two of the constructs were not transferred to E. coli BL21and after several attempts we did not proceed, which left 17 successfultransformants.

We also separately PCR-cloned from Campylobacter jejuni 11168. ThusCj0404, Cj0788, Cj0892 and Cj0424 were cloned into plasmid with his-tagand transformed into E. coli BL21. Previous work suggested that Cj0404was antigenic (Clin Vaccine Immunol. 2012 February; 19(2):113-9) whereasCj0424 was identified by us.

Preliminary tests were performed with the 4 C. jejuni genes transformedin BL21.

Further, several inductions were made with the 17 C. jejuni genestransformed in E. coli BL21. Media and induction protocols were tested.“Magic media” was seen to induce relevant sized proteins as can be seenfrom the SDS gels shown in FIG. 1. It was demonstrated that 7 C. jejuniclones were induced (circle markings). Overnight cultures were run onthe 12% SDS gel. All experiments were performed at least twice withessentially the same results.

Protein Purification and Verification of Immunogenicity

The C. jejuni transformed clones were tested for antibody recognition ina dot blot assay.

The four selected clones produced from PCR cloning were tested forexpression and antibody antigenicity in a dot blot assay against humansera (dot blot 1 shown in FIG. 2).

The 7 E. coli clones that could be induced to produce C. jejuni proteinswere tested for reaction with antisera from rabbits immunised with fivedifferent Campylobacter strains of five different isolates. All clonesreacted to all sera.

All experiments were performed at least twice with essentially the sameresults.

Since all antigens were recognised by rabbit antisera, they weresubsequently tested with sera from patients that were shown to haveantibodies against Campylobacter jejuni tested in the diagnostic testthat runs at the Danish State Serum Institute (Strid et al. Clin DiagnLab Immunol. 2001 March; 8(2):314-9).

The sera were randomly picked but all exhibited antibodies againstCampylobacter jejuni. Patients with no antibodies to C. jejuni by ELISAare not expected to react in the dot blot assay (data not shown).Examples of the dot blots are seen in FIG. 2.

From the dot blots it is seen that all patients found to have antibodiesagainst C. jejuni by a diagnostic ELISA react also react with coloniesof E. coli BL21 that express C. jejuni antigens. In many cases thenegative control being an E. coli BL21 without a plasmid is seen to alsoreact with the sera This is expected since humans have encountered E.coli infections and are colonised in the gut.

IN CONCLUSION

We have identified 30 C. jejuni genes that are be potentially antigenicand recognised by antibodies against Campylobacter. We have been able toshow that 7 of these are indeed able to be recognised by antibodiesraised in humans after a natural infection with Campylobacter jejuni(diarrea).
